Edge

public Edge(Node nodeSrc,
            Node nodeDst,
            float weight)

Constructor to create an Edge from a Node to another Node with the specified weight.

Parameters:

nodeSrc - is the source Node.

nodeDst - is the destination Node.

weight - is the weight of the Edge.

Method Detail

getSourceNode

public Node getSourceNode()

Get the source Node of the Edge.

getDestNode

public Node getDestNode()

Get the destination Node of the Edge.

getWeight

public float getWeight()

hashCode

public int hashCode()

Get a hashcode for this Edge.

Overrides:

hashCode in class Object

Returns:

Returns an int containing the hashcode for this Edge.

toString

public String toString()

Returns the name of the Edge.

Overrides:

toString in class Object

equals

public boolean equals(Object o)

This method checks if a given object is the "same" as this one. If the two Edges have the same name, then they are considered the same.

Overrides:

equals in class Object

Parameters:

obj - is the Object to check for equality.
